Moto-House MX Pro Tip:

A slip-on upgrade is the best way to improve your TRX450R's weight-to-power ratio. Installation Tip: Ensure the slip-joint connection is clean and properly sealed with a high-temp exhaust gasket or sealant to prevent leaks. Tuning Advice: Because the TRX450R responds well to increased airflow, we highly recommend re-jetting your carburetor (for carb models) or using a fuel programmer (for EFI models) to achieve the perfect air-fuel ratio for maximum power gains.
